The status of the Beckhoff IOCs was missing from the control room. This was highlighted by their slow recovery following the power outage last week. As a first attempt to make them more visible, I have added their current time EPICS channels to the CDS STATE_WORD overview MEDMS (large and small versions). This immediately paid off, as we found the end station IOCs were not actually running, Daniel restarted them. We also noticed the OPI computers' times were off from each other by 2 seconds, so we need to NTP these machines today.

Hopefully better diagnostic channels, like UPTIME, can replace the current time on the overviews.

For the purposes of integrating Beckhoff "front ends" with the DAQ FE, I'm going to make a "GDS" screen per PLC which gives top level status info like STARTTIME, CODELIST, etc.
